The start: 0 to 100 km/h

Off the line, the 330i hits 100 km/h in 5.88 s versus 9.87 s for the A3 Sedan. At this point, the 330i leads by 3.99 s and sits roughly 24 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 330i is doing 135 km/h against 108 km/h for the A3 Sedan. The gap is 1.96 s. The challenger starts to claw back ground.

At 400 metres standing start, the 330i crosses the line in 14.04 s versus 17.21 s. The 3.17 s gap represents roughly 112 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 330i continues to build its lead. At 600 metres, it runs at 190 km/h versus 150 km/h. At 1,000 metres, the 330i finishes in 25.09 s versus 31.24 s, with a 6.15 s lead.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the 330i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.70 kg/hp vs 11.68 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.25 seconds. The 3.99 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
